Definitions
- the present invention relates to an anti-counterfeit security device for documents in general.
- security devices are currently inserted in many documents, such as for example bank notes; these devices are constituted by filaments with such characteristics as to increase the difficulties in reproducing these documents.
- European Patent No. 310,707 which in practice consists in depositing, on a support made of flexible and impermeable material, such as for example a polyester tape, regions of magnetic material, such as iron oxide, which either due to their different thickness or due to their different deposition area have, when passing beneath a magnetic head, a signal/flux directly correlated to the amount of oxide, taking into account that the filament is generally manufactured with a constant width.
- These regions of magnetic material are magnetized by means of a permanent magnet which in practice charges the iron oxide so that it maintains the magnetic flux in order to be a signal-emitting element.
- the signals are detected by magnetic heads which, by means of appropriate electronic devices and associated programs, allow to form a decodable code, according to the thickness, density, position and/or succession of the magnetic regions.
- these regions In order to detect the magnetic flux of the regions composed using iron oxide, these regions must be moving beneath the magnetic head; this movement increases the signal as a function of the speed in a substantially proportional manner.
- this security device is detectable only by means of specifically dedicated devices, and in practice cannot be detected visually, since, as mentioned above, visually it is only possible to identify the presence of a filament, without however being able to determine whether it has the required characteristics.
- Another known solution uses an impermeable flexible support, constituted by a polyester tape or filament, provided with a continuous metal layer that makes said filament conductive and therefore detectable by an apparatus which, however, can only detect the presence or absence of said filament.
- the metal layer has regions without metal which in practice form graphic signals, for example letters or the like, which are visually perceivable and thus detectable directly without using an apparatus.
- the regions without metal i.e. the regions that form the graphic markings, must be fully surrounded by metal in order to avoid altering the metallic continuity of the filament.
- the metal layer can also be obtained by depositing metals through evaporation.
- the document obtained by inserting the filament inside the paper has the particularity that the presence of the filament cannot be detected when it is examined in reflected light, whereas in transmitted light the graphic signals are perfectly legible.
- a considerable problem for this filament is constituted by the fact that it is relatively easy to counterfeit it, since the materials required to form the metal layer and the corresponding graphic markings are normally commercially available; these counterfeits can easily deceive both personnel, when performing a visual inspection, and the equipment for detecting the presence or absence of the filament inside the document.
- the first one i.e. the one provided with the magnetic regions
- the other filament instead can be decoded visually by personnel and can be detected by means of an apparatus that allows to check for the presence of the filament, but on the other hand can be counterfeited in a relatively easy manner.
- a principal aim of the present invention is to solve the problem described above by providing an anti-counterfeit security device for documents in general that can both be decoded by appropriate devices, providing a high degree of intrinsic security, and be decoded visually by virtue of the possibility of detecting graphic markings perceivable in transmitted light.
- Another aim of the invention is to provide a security device that combines the typical characteristics of the known art in two separate elements, allowing to provide a single element, i.e. in practice a single filament having both characteristics.
- Another aim of the present invention is to provide a security device allowing to further increase the security characteristics, offering a wide range of combinations, all of which are aimed at making the document safer by virtue of the practical impossibility for a counterfeiter to detect the security elements.
- Another aim of the present invention is to provide an anti-counterfeit security device for documents in general that can be obtained with simple techniques and can be inserted inside the document like the filaments conventionally used up to now.
- an anti-counterfeit security device for documents in general in the form of a tape-like supporting element comprising: a first security element detectable by devices and constituted by regions that are made of a material which can be detected by magnetoresistors and are arranged in succession to generate a signal that can be decoded by said magnetoresistors; and a second security element, detectable in transmitted light, which is constituted by portions of said regions which are free from said magnetoresistor-detectable material in order to form graphic markings that can be perceived optically in transmitted light.
- the anti-counterfeit security device for documents in general comprises a supporting element, designated by the reference numeral 1, which is advantageously constituted by a filament or tape made of flexible and impermeable material, for example polyester.
- a first security element that can be detected by devices specifically equipped for this purpose is provided on said filament 1 on one of its faces or possibly on both.
- Said first security device is constituted by regions, designated by the reference numerals 2a, 2b and 2c, which are made of a material detectable by magnetoresistors.
- Said material is constituted for example by a printable ink containing iron dust.
- the various regions 2a, 2b and 2c are formed with different thicknesses and with different percentages of iron dust; these percentages can be constituted, for example, by 15%, 30% and 50% of iron dust mixed in a reflective ink containing some aluminum parts, generally 3%.
- the various regions made of magnetoresistor-detectable material i.e. containing iron dust, are placed in succession so as to form a signal that can be decoded by the magnetoresistors, which can in practice detect, by means of a static measurement, i.e. with no relative motion between the read head and the support, a signal variation produced by the different amount of iron dust, i.e. by the different amount of the material detected by the magnetoresistor.
- a second security element that can be detected visually in transmitted light and is constituted by portions 10 which are free from said magnetoresistor-detectable material, so as to form graphic markings, symbols, letters of the alphabet and so forth, that can be perceived optically in transmitted light.
- said magnetoresistor-detectable material contains iron dust that is ground with a particle size of less than 15 microns, since the finer the pulverization of the iron dust, the higher the optical definition of the lettering and the higher the uniformity of the signal detected by the magnetoresistors.
- an additional security element constituted by regions made of magnetic material 20 which are constituted for example by an iron-oxide ink, so as to produce a code that can be detected by a magnetic read head.
- the magnetic regions must be arranged so as to not interfere with the portions that are free from the magnetoresistor-detectable material, thus without hindering the optical detection of the graphic markings in transmitted light.
- a security device in which said magnetic regions forming a code are provided on a filament, again designated by the reference numeral 1, in which the graphic markings that can be perceived in transmitted light are printed with normal printing ink 30, thus creating two security devices: a magnetic one, that can be detected by magnetic read heads, and an optical one that can be detected against the light.
- the invention achieves the intended aims, and particularly the fact is stressed that a security device is provided that allows, if regions formed with iron dust are used, to perform static-type reading by means of magnetoresistors, since it is possible to create a code by varying the percentages or amounts of iron dust provided in the various regions.
- Another important object of the invention is furthermore constituted by the fact that the security device can be provided visually, by virtue of the possibility of detecting the lettering or graphic markings in transmitted light, on a tape that cannot be counterfeited, since the remaining portions have depositions of material forming a code that can be decoded only by specific devices.
- the materials employed, as well as the contingent shapes and dimensions may be any according to the requirements.
